DVR (AX014ANM) (4k) TV video shoved off to the right with every daily auto-restart

I recently upgraded my Xfinity set-top DVR box to the 4k version (AX014ANM). (I don't have a 4k TV yet, I simply wanted the latest and greatest DVR from Xfinity, just in case I get a 4k TV someday.) Every morning when I turn on the TV (which is 1080p, not 4k), the TV video is shoved off to the right, a little less than halfway across the screen, with black filling the remaining area on the left of the screen. If I change the channel, to any other channel, the picture resets and fills the screen like it's supposed to. This has been extremely annoying!

I suspect the reason is because of the AX014ANM's forced daily auto-restart, which probably puts it into 4k mode by default, until I turn on the TV for the first time that day, and then the DVR detects that it is NOT 4k and then resets the Xfinity video to 1080p.

In my settings for the DVR, it clearly lists 1080p as the Best Resolution. Yet when the DVR auto-restarts, it doesn't care about that setting and appears to boot into 4k anyway.

I should not have to change my channel the first time I turn on my TV every day, just to get the picture to center itself!

Please fix this!!
